The video of Lee, 29, telling his first child to "stay strong" and consoling him, has gone super viral with more than 10 million views.

"I felt his pain but at the same time, it was all about love," the Warrenton, Georgia, dad told ABC News. "I know he felt the love because his daddy was there."

Lee said aside from this viral moment, his son rarely cries "unless he's hungry."

"When I hold him and when I talk to him, he just sits there and listens. This is my first time," the father said, adding that since he's a first-time dad, he didn't expect that his son would "be this type of angel."

Lee said it's "amazing" that his video has gone viral, especially since the day of the doctor's visit was a hard day for him. But it also put fatherhood into perspective.

"That night I [spoke] to my son -- he's only 2 months -- and I let him know: 'Son, I want to see you succeed before I die,'" Lee recalled. "I've got to see you succeed."
